Extremely sorry, I mentioned the wrong port in that post.. Actually I am
using the correct port number..
Client (Windows + non SSL):8091 ==> Nginx host (ubuntu vm+ SSL redirection)
==> TCP server (Windows + SSL enabled)
TCP server listening on 8091
Nginx Server listening on 8091
Client makes call to Nginx on 8091
I modified my server code for additional debugging as below
#################
ServerSocketFactory ssf = SSLServerSocketFactory.getDefault();
int port = 8091;
ServerSocket ss = ssf.createServerSocket(port);
while (true) {
try {
Socket sock = ss.accept();
System.out.println("Timeout set is " + sock.getSoTimeout());
System.out.println("New client connected");
PrintWriter pw = new PrintWriter(sock.getOutputStream());
pw.println(new Date().toString() + " from port: "+port);
System.out.println("Data ready to sent to client");
pw.flush();
//pw.close();
System.out.println("Data sent to client");
System.out.println("Ready to read client data");
BufferedReader br = new BufferedReader(new
InputStreamReader(sock.getInputStream()));
String data = br.readLine();
System.out.println("Data received from Client: "+ data);
//br.close();
sock.close();
System.out.println("Socket closed");
########################
Output from the server when client initiated the connection is..
#####################
Timeout set is 0
New client connected
Data ready to sent to client
Data sent to client
Ready to read client data

Are you able to run a similar configuration?
May be I would have done something wrong on SSL settings or on self-signed
certificate. Let me start things from scratch again..
